The 'Nobody's Perfect' hitmaker has revealed both she and her family have been targeted by hate-filled individuals since she achieved pop success, but she refuses to waste her time worrying about what might happen to her.

In an interview in Q magazine, she said: "I've had people say, 'I wanna kill you and your family.' Death threats. I've had people say, 'I Hope you get HIV and throat cancer at the same time.'

"I think the world has become obsessed with hating things. But people who wanna spread bad energy, I ain't got time for them to be in my psyche."

The 23-year-old star - who is openly bisexual and abstains from drinking alcohol because of health problems she has suffered, including having a minor stroke aged 18 - has also revealed there have been rumours she is a devil worshipper because she makes an OK sign with her hands in her video for single 'Price Tag'.

She said: "This is 666 apparently. And to me it's saying OK. People have played 'Do It Like a Dude' backwards and said they can hear the devil."
